Y Specification of Letters Patent. Patented Aug. 30 192L Application filed November 10, 1920. Serial No. 423,087.

To all whom t may concern.'

Be it known that I, CHARLES L. ToRREY, a citizen of the United States, and resident of San Jose, in the county of Santa Clara and State of California, have invented certain new and useful Improvements in Burner- I-Ieads, of whichr the following is a spec1fication.

My invention relates to a head for gas burners of any suitable type. l

It is the object of my invention to provide a burner head for any form of gas that will be simple in form, economical to manufacture and highly efficient in its practical application.

In burning any formA of natural or artificial gas, and especially that form of gas generated in the various forms of hydrocarbon gas generators now in general use, it is customary to provide a burner head in which the discharge openings for the gas are formed by sawing slots or drilling holes in a suitably formed cast-iron plate. This process is ordinarily a slow, laborious and eX- pensive undertaking, frequently many saws being destroyed in the preparatlon of a smgle head. It is, therefore, a particular object of my invention to provide a highly efficient and practical burner head that will obviate the necessity of sawing the slots or drilling the holes` above referred to.

In the drawing Figure 1 is a plan view of a burner head embodying my invention.

Fig. 2 is a sectional view on line 2 2 of Fig. 1.

Referring more particularly to the drawing, 1 indicates a gas chamber of any'suitable form into which the gas to be burned is discharged through passage 2. At 3 is a plate of the same size as the top of chamber 1 and provided with a plurality of orifices as 4. A second plate is shown at 5 tting in the upper portion of chamber 1 and provided with a plurality of orifices 6, and spaced a distance, as 7 from plate l3 by suitable spacers as 8, and from the wall of ehamber 1 by a space as indicated at 8a. A bolt is shown at 9 threaded to engage nuts 10 and l1, the nut 11 securing plates 3 and 5 in the desired relation to each other and nut 10 securing the plates in position on the chamber 1.

If the space 8 is provided the orifices 6 may be dispensed with, and if the orifices 6 are provided the space 8aL may be dispensed with, or both space 8a and orifices 6 may be provided. In fact, when the members 3 and 5 are 1n position on chamber 1 the space 8a is the full equivalent of orifices 6.

In effecting my invention the orifices 4 in plate 3 may be of any suitable size and arranged in any desired manner, and may be cast in the plate and used without any mechanical operations thereon. The orifices in plate 5 may likewise be of any suitable size and arranged in any desired manner except that they must be so arranged that when the plates are assembled as described the orifices in plate 5 will be offset with relation to the orifices in plate 3.

In a head constructed in this manner the gas is discharged forcibly from chamber 1 through orifices 6 and against plate 3 where it is caused to spread out and flow with less velocity through orifices 4, since the orifices 4 are, in this case, larger than orifices 6. When a gas that is generated from fuel oil is being used a practically perfect combustion thereof is secured since the plate 3 is heated by the burning gases thereover and the im` pinging of the gas against the under side of this heated plate more perfectly vaporizes the same.

The space between plates 3 and 5 must, of course, be such that the gas cannot back-fire even though the gas burns directly from the surface of plate 5 through orifices 4. In this construction the plate 5 also becomes somewhat heated and the gas must pass a distance between the two heated plates 3 and 5 before reaching orifices 4 thereby.

A burner head constructed in this manner provides a clean hot fiame and requires only the plain casting and assembling of the parts, thereby greatly simplifying and reducing the cost of the head without in any manner reducing its efficiency but rather increasing the same.

It is to be understood of course, that I do not wish to limit the scope of my invention to the specific form disclosed, as changes in form, size, proportions, and combination and relative arrangement and association of parts, members and features may be made within the scope ofthe appended claims.

I claim 1. A burner head comprising a bowl shaped member, a gas inlet thereto, a perforated plate arranged to cover the bowl shaped member, a second perorated plate spaced a distance from said first named plate and dei pending,` therefrom within said bowl shaped member, and means engaging both of Said plates and said bowl shaped member yfor Securing the Same in iXed relation to each other.

2. A burner head comprising a bowl shaped plate arranged -t-o kcover the bowl shaped member, a second perforated plate arranged withinsaid bowl shapedy member below isaid irst mentioned plate, spacing elements between Said plates, and a tie member axially 15 arranged with relation to said plates and bowl shaped member.
